Dec. 5, 1967 CHAMPAGNE DRAIN PIPE CONNECTION Filed Jan. 3, 1966 INVENTOR. LEONA/9D CHAMPAGNE A T 7 ORNE Y5 United States Patent 3,356,225 DRAIN PIPE CONNECTION LeonardChampagne, 1592 Bailey Ave., Bufialo, N.Y. 14212 Filed Jan. 3, 1966, Ser. No. 518,158 1 Claim. (Cl. 210448) This invention relates to a drain connection and in particular to a drain pipe connection having a readily accessible and removable strainer, the combination being adapted for use for connecting between a generally upright drain pipe and a soil pipe.

Heretofore, strainer devices used in connection with drain pipes or downspouts have often been positioned near the top thereof adjacent the eaves of a building and when clogged with leaves, twigs or the like the inaccessibility of these strainer devices necessitates inconvenient and sometimes costly removal of the clogging material therefrom. Moreover, due to the insufiiciency or deterioration of some strainer devices, drain pipes are sometimes clogged at points beyond the strainer devices and the use of an auger or other drain clearing apparatus thus necessitated is, at best, awkward and may prove to be ineffective. Even where such strainer devices have been disposed in more convenient positions, access to the strainer device has been limited by the necessities of good drainage construction and usually has required a great deal of manipulation of the drain pipes, drain connectors or the like in order to provide such access. Oftentirnes, even with such manipulation the strainer devices cannot be removed for replacement thereof without dissembly of a substantial portion of the drainage system.

To overcome such difficulties, it is an object of the present invention to provide a drain connection comprising a drain connector and strainer disposed between the lower end of a downspout or drain pipe and a soil pipe in a manner as to provide ready accessibility to the strainer and easy removability thereof for cleaning, repair, or replacement.

It is another object of the present invention to provide a drain connection of the foregoing characteristics having a strainer adapted to seat on the upper end of a soil pipe and a drain connector adapted to slidably and telescopically receive the lower end of a drain pipe for moving the drain connector slidably upwardly above the strainer and soil pipe to expose the strainer for cleaning, repair or replacement. Moreover, the telescopic relation between the lower end of the drain pipe and the connector provides a connection adaptable for use with variably spaced drain and soil pipes and negates any requirement for a critical length relation therebetween.

It is a further object of the present invention to provide a drain connection of the foregoing characteristics having a cup-shaped strainer disposed within the usual upper bell portion of a soil pipe with an upper lip portion thereof resting on the soil pipe and a drain connector having concentric members disposed within the soil pipe and cupshaped strainer and encircling the bell portion of the soil pipe, respectively, whereby transverse movement of the drain connector relative to the soil pipe is effectively prevented.

Various other novel details of construction and advantages inherent in the drain construction of the present invention are pointed out in detail in conjunction with the following description of a typical embodiment of the invention. While one embodiment of the present invention is illustrated in the accompanying drawing and described in the following specification, it is to be understood that such embodiment is by way of example only and to illustrate the principles of the present invention, the scope of which is limited only as defined in the appended claim.

The single figure of the drawing is a vertical cross- 3,356,225 Patented Dec. 5, 1967 sectional view of one form of the drain pipe connection construction of the present invention and fragmentary portions of a drain pipe and soil pipe.

The lower end of a conventional drain pipe or downspout such as is used in roof drainage is indicated by reference numeral 1 and the exposed upper end of a conventional soil pipe is indicated at 2, the latter terminating in an enlarged upper portion or bell 3. The lower end of drain pipe 1 is spaced above the bell 3 of soil pipe 2 a distance sufiicient to place the strainer connection of the present invention therebetween and to give access for a plumbers snake or roto-rotor when such is required.

The drain connection includes a drain connector generally indicated at 4 which includes a tubular member 5 having an upper end of such a configuration relative to the lower end of the drain pipe as to slidably receive the lower end of the drain pipe. Member 5 has a length sufficient to connect between the lower end of drain pipe 1 and bell 3 and has a lower portion 6 which extends within and opens directly into bell 3 thereby providing a leakproof non-restricted connection between drain pipe 1 and soil pipe 2. The telescopic relationship between member 5 and the lower end of pipe 1 adapts the connector for connection between variably spaced drain pipes and soil pipes within the limits imposed by the length of member 5.

An outwardly radially extending flange 7 is provided intermediate the ends of tubular member 5' and adjacent the lower portion 6. An annular flange 8 depends from the periphery of radial flange 7 and is coaxial with lower portion 6 of tubular member 5. Circumferential flange 8 surrounds the enlarged portion or bell 3 of soil pipe 2 and forms, with radial flange 7 and concentric lower portion 6, a downwardly opening annular recess for purposes hereinafter described.

Sheet metal material may be utilized in the construction of the connector in which case flange 7 has an enlarged diameter portion 9 which locates the flange 7 on member 5. The flanges 7 and 8 are secured together and flange 7 is secured to member 5 below portion 9, each by suitable means, such as soldering, Welding or the like, to form a rigid integral connector unit.

The tubular member 5 and the associated flanges may also be formed of plastic material in which case the drainage connector 4 would be of unitary construction. Such plastic construction affords a rust-free, light-weight, durable and low-cost connector.

A strainer generally indicated at 10 is of a wire mesh construction having a fineness sufiicient to strain out debris which would tend to clog the soil pipe. The strainer, in the preferred form, is an upwardly opening cup-shaped member having upstanding walls 11 and an outward radially extending annular lip 12 at the upper peripheral portion thereof. The walls 11 have a diameter larger than the diameter of lower portion 6 of tubular member 5 and freely receive same when in use. The strainer is supported on the soil pipe by lip 12 which seats on the upper surface of hell portion 3 and is releasably secured in assembled position by radial flange 7 of the connector.

In arranging the drain connection of the present inventionfor use, strainer 10 is placed with-in the bell 3 of soil pipe 2 with lip 12 seating on the upper surface of bell 3. The tubular member 5 is then slid downwards onto hell 3 so that the sides of the bell and walls 11 of strainer 10 enter into the annular recess formed by the concentrically arranged flange 8 and lower portion 6. The underside of radial flange 7, upon further downward movement of member 5, engages the lip 12 of strainer 10 and releasably secures same between flange 6 and the upper surface of bell 3. Such engagement forms a seal against the ingress of foreign material from without the drain connection. Moreover, the seal is spaced above the lower end of member 5 and the drainage flowing through the drain pipe, drain connection and soil pipe, does not nor mally come into contact therewith. Thus there is provided a leakfree and environmentally sealed strained drainage passage connecting between the drain pipe and the soil pipe.

It is an important aspect of the present invention that the strainer be readily accessible and removable for cleaning and repair. By merely raising the connector and telescoping same on the drain pipe, the strainer is exposed for cleaning and is readily removable from hell 3 without further manipulation. Moreover, by positioning the walls 11, and lip 12 of the strainer and the bell 3 Within the annular recess formed by flange 8 and lower portion 6, transverse movement of the strainer connection relative to the soil pipe and slippage of the strainer from a straining position is precluded.

Having thus described and illustrated a preferred embodiment of my invention, it will be understood that such description and illustration is by way of example only and that such modifications and changes as may suggest themselves to those skilled in the art are intended to fall within the scope of the present invention which is limited only by the scope of the appended claim.

I claim:
